Abstract: PURPOSE: A method for fabricating a capacitor having a tantalum oxide layer as a dielectric layer is provided to eliminate the impurities contained in a layer by performing a high temperature heat treatment process after the tantalum oxide layer is formed, and to remove oxygen vacancy by performing a low temperature heat treatment process. CONSTITUTION: A lower electrode is formed. The tantalum oxide layer(41) is deposited on the lower electrode by a low pressure chemical vapor deposition(LPCVD) method. The first heat treatment process is performed on the tantalum oxide layer at a temperature of 500-700 deg.C. The second heat treatment process is performed on the tantalum oxide layer at a temperature of 300-500 deg.C after the first heat treatment process.
